104 REVISION OF SYMPETES AND HEL^US, ETC., 



suture also costate but less raised than preceding, surface of disc 

 closely, coarsely and confusedly punctured, with two equidistant 

 lines of punctures between the costse and margins, interrupted 

 and confused with the rest at base and apex, but forming with 

 the rugose intervals two short indistinct lines near centre; a row 

 of lateral punctures placed in a deeply indented sulcus; epipleurse 

 and overlapping sides of sternum very coarsely punctured, with 

 intervals rugosely vermiculate; abdomen finely rugose, with faint 

 longitudinal strigose aspect. Legs normal. Dimensions 16 x 

 12-5 mm. 



Hab. — King George's Sound, West Australia. 



A unique specimen, female, in the Macleay Museum, labelled 

 H. Ferr onii ^oisd.; but this identification is in glaring defiance 

 of the description and figure as given by de Breme.* It is 

 evidently nearest to H. castor Pasc , in its ovate form and 

 depressed thorax, while it differs from that species in (1) smaller 

 size, (2) less circular form, (3) closer elytral costae, etc, I have 

 named it after the veteran Curator, Mr. George Masters, while 

 its name will also suggest its habitat. 



Hel^us Gilesii, u.sp. 



Broadly ovate, convex, nitid, black above, piceous-black 

 beneath, tarsi and apical joints of antennae reddish. 



Head with labrum emarginate and truncate, with rounded 

 angles, epistoraa truncate and rather flat, rounded at the sides, 

 epicranium forming a subtriangular plate between and continued 

 in front of the eyes on the same plane as the eyes, part between 

 this and the epistoma rather abruptly depressed; eyes large, 

 separated by less than 1 mm., antennae not extending to the base 

 of prothorax, third joint cylindrical and slender, 4-7 obconic, 

 slightly increasing in width, 8-11 subspherical, forming a club 

 much wider than the rest, eleventh largest and not at all pointed. 

 Prothorax transverse(6 x 10 mm.), width measured at base, length 



* The above was written before receiving the (I believe) true H. Perronii 

 from Mr. Gahan. H. Georgei is still further removed from this species.
